I'll try to find the post, but I'm pretty sure Dan mentioned that BMW weren't getting any power increases with the performance intake, and when the engine was warmed up, they were losing power.

If that's the case, then I can't seen anyone wanting to shell out several hundred for an admittedly cool looking intake, unless they happen to have had a transparent bonnet installed so you can actually see the thing!

Not wanting to hijack the thread, but just wanted to ask how the Superchip is going. Still happy? Want even more power now that you've had a taste of the good life?!

The Superchip is great, I've had no issues whatsoever with it (touch wood).
The only thing to keep in mind is that with the chip then engine is fussy over the type of fuel you put in. Octane 97 or above is fine. Put anything lower in, and you will see the acceleration degrade.

I'd like a beefier sounding intake and exhausts now, but am happy to see what develops. I couldn't throw away a perfect exhaust to make way for the performance one, not until it's worn out anyway.
